Front Panel Indicators
- Service LED: Indicates cellular service status. (e.g., Solid Green: Connected, Blinking: Attempting connection, Off: No service)
- Signal LED: Indicates cellular signal strength. (e.g., Green: Strong, Amber: Medium, Red: Weak)
- Power LED: Indicates power status. (e.g., Solid Green: Power on, Off: Power off)
Ports and Connectors
- Ethernet Port (LAN): One RJ45 port for wired network connection.
- Power Input: Connector for the DC power adapter.
- Antenna Connectors: (Not visible in image, but typically present on cellular routers for external antennas, though this model states "NO Antenna" in description, implying internal or separate purchase). Note: This model does not include antennas. External antennas must be connected to the appropriate ports (if available) for cellular connectivity.
5. Setup
Initial Setup
- Positioning: Place the router in a central location, away from obstructions and other electronic devices that may cause interference. Ensure good cellular signal reception.
- SIM Card Installation: If applicable, insert your activated 4G LTE SIM card into the designated SIM card slot. Ensure it is inserted correctly according to the diagram on the device or in the Quick Start Guide.
- Antenna Connection: If using external antennas (recommended for optimal performance, and necessary for this model as it ships without antennas), connect them securely to the antenna ports.
- Power Connection: Connect the power adapter to the router's power input port, then plug the adapter into a power outlet. The Power LED should illuminate.
Network Connection
- Wired Connection: Connect an Ethernet cable from the router's LAN port to your computer or network switch.
- Verify Connectivity: Once powered on, the router will attempt to establish a cellular connection. Monitor the Service and Signal LEDs. The Service LED should turn solid green, and the Signal LED should indicate good signal strength.
6. Operating Instructions
Basic Operation
Once the router is powered on and has established a cellular connection (indicated by the Service and Signal LEDs), devices connected to its Ethernet port will be able to access the internet via the 4G LTE network.
Accessing the Web Interface
For advanced configuration and monitoring, you can access the router's web-based management interface:
- Ensure your computer is connected to the router via Ethernet.
- Open a web browser (e.g., Chrome, Firefox, Edge).
- In the address bar, type the router's default IP address (commonly
192.168.1.1or192.168.0.1, refer to the Quick Start Guide or device label for the exact address) and press Enter. - Enter the default username and password when prompted (typically
adminfor both, or as specified in the Quick Start Guide). - You can now configure network settings, security, and monitor device status.
7. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your router:
